BOB SLEIGli.

SPECIFICATION forming part of Letters Patent No. 298,849, dated May 20,188

Application filed October 12,1883.

To all whom it may concern Be it known that I, EDWIN A. HARDING, a.citizen of the United States, residingat Harbor Springs, in the countyof Emmet and State of Michigan, have-invented certain new and usefulImprovements in Bob-Sleighs; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make aiidnsethe same.

This invention relates to improvements in bob-sleighs, and has for itsobject to permit of an independent rocking motion to the runners. Thisobject is accomplished by the mechanism illustrated in the accompanyingdrawings, forming a part of this specification,in which Figure 1 is aside elevation. Fig. 2 is a section of beam B. Fig. 3 is a plan; Fig. 4,a de tailed view of beam B. Fig. 5 is a sectional view of brace O andbeam B.

The letter A indicates the runners; B, a cross-beam; O, braces; D, yokesor standards; E, the bolts which secure the braces O to the runners A. I

The runners A are provided with blocks A, having notches of semicircularform on the upper side, which form resting places for the beamB, whichextends across the runners A, and the ends of which are provided withnotches B, into which the upper edges of blocks A are fitted, and thusaid to hold the runners in a vertical position and the proper distanceapart. The braces C extend over and slightly above the beam B and piecesor blocks A, and then downwardly at each end, to conform to the shape ofthe runners,to which they are secured by means of the bolts or rivets E,

] and have also the yokes or standards D,which enter grooves F in eachside of the beam B and serve to hold and support it in the properposition, and at the same time to permit it to turn partly on its axisor allow the runners A to accommodate themselves to any inequalitieswhich may exist on opposite sides of the road.

The yokes D may be of U shape, and be secured to the blocks A in anysuitable manner; or they may be simply suspended by the braces O, andform bearings in which the beam B may oscillate without coming incontact with the blocks A on the under side. I11 another form the yokesor standards D may be straight bolts driven into the blocks A andsecured at the top by the braces O. N

Having described my invention, what I clesire to secure by LettersPatent and to claim In a bob-sleigh, the beam B,- having notches B,rounded on the lower side and adapted to fit down upon and into asemicircular recess on top of the blocks A, secured to the upper sidesof the runners A, said beam having grooves F, rounded at the bottom,thereby permitting it to oscillate upon the yokes D and block A, incombination with runners A, provided with braces O, as shown anddescribed.

In testimony whereof I affix my sign atnre in 'presence of twowitnesses.

EDIVIN A. HARDING.
